In trying to calculate the power of a single horse, Watt began by watching mill horses at work. Lashed to the spokes attached to the mill's central machine drive shaft, the horses turned the shaft by walking in a 24foot diameter circle, approximately 144 times in an hour. Watt estimated that each horse was pushing with a force of 180 pounds.
